SUNNYVALE, CA--(Marketwire - January 23, 2009) - Leadis Technology,
Inc. (NASDAQ: LDIS) today announced a new agreement with Immersion
Corporation (NASDAQ: IMMR) to enable rapid implementation of
high-quality haptic feedback in capacitive touch enabled devices
ranging from portable devices, such as mobile phones and personal
navigation devices, to non-mobile products, such as multi-function
printers and white goods. Leadis also introduced the LDS6018 and
LDS6048 capacitive controllers, two new TouchSense®-ready members of
the PureTouch(TM) family.

Under the agreement, Leadis receives a license for Immersion's
proprietary TouchSense® Player and Haptics Effect Library which will
extend to customers purchasing Leadis' haptic driver integrated
capacitive touch controllers. Combining software and hardware into a
single offering allows end-product manufacturers to quickly
incorporate a standard library of tactile feedback effects for
capacitive touch inputs. Optional professional service packages will
also be offered for customers desiring custom effects or optimization
for non-standard implementations.

The previously announced LDS6010 (touch controller with integrated
TouchSense®-ready haptic driver) and LDS6040 (touch controller with
integrated TouchSense®-ready haptic driver and keypad LED drivers)
will support portable implementations requiring up to 3.6V direct
drive voltage. The newly announced LDS6018 and LDS6048 will support
non-mobile applications requiring more powerful actuators and higher
direct drive voltages up to 5.5V. Both LDS6018 and LDS6048 contain 15
sensor input channels and an integrated TouchSense®-ready haptic
driver, with the LDS6048 adding keypad LED driver functionality on
eight of the 15 sensor inputs.

"The addition of tactile feedback to touch controls significantly
enhances the user experience, and Immersion is clearly the leader in
haptics technology," said Alvin Wong, Vice President and General
Manager for Touch at Leadis Technology. "Combining Immersions' haptic
playback software, effects library, and technology license with our
TouchSense®-certified touch controller provides our customers with a
proven and highly scalable solution to achieve best-in-class haptics
and a truly compelling user experience."

"We believe this agreement will provide a valuable channel to extend
Immersion's reach and accelerate adoption of our proprietary touch
feedback technology," said Craig Vachon, senior vice president and
general manager of Immersion's Touch line of business. "Leadis is the
first touch controller manufacturer to integrate a
TouchSense®-certified haptic driver, and we're pleased to extend our
relationship with this new agreement."

About the LDS6018 and LDS6048

The LDS6018 is a programmable touch controller with integrated
TouchSense®-ready haptic driver for use with capacitive sensor arrays
implementing touch-based input controls including sliders, scroll
wheels, and buttons. The LDS6048 offers the same functionality as the
LDS6018, with the addition of integrated keypad LED driver
functionality. Both devices feature 15 sensor inputs, fast update
rates of 2ms per sensor input, and on-chip automatic calibration
logic to continuously monitor the environment and adjust ambient
baseline levels for increased touch accuracy.

Eight of the 15 sensor inputs on the LDS6048 are configurable as LED
drivers capable of driving up to 8mA of current, with > 60mA
available for a single LED by combining multiple LED drivers
together. Automatic LED activation upon a valid touch is achieved by
associating an LED driver to a sensor input. A full array of dimming
options is also supported.

The LDS6018 and LDS6048 offer extremely low power consumption without
the introduction of touch latencies. Each device consumes less than
150µW of power (typical) in full power mode (touch sensor power
consumption, haptics driver in shutdown). Both devices are packaged
in 5mm x 5mm 40ld TQFN packages with maximum thickness of 0.8mm.
